Hello
I am working on the following Problem: I have two ati 5870 cards. On one I have connectet 1 Monitor via DVI, on the other I have connected two via DVI. Unfortunately I cant all of the three working at once. I know there is quite some material in the web on this topic but even do i was trying and searching quite extensively for some time i could not find a solution.
Depending on my xorg.conf file (i tried quite a lot of configurations) only one or the other two are working. with the following xorg.conf file on is displaying the graphical stuff an the other two just a black terminal where i can not start an xserver:

Any help on this topic would be appreciated. Thank you a lot.
